The device has already been successfully tested in a four-week study. The results showed that the controlled release of the repellent transfluthrin was effective in preventing the entry of several mosquito species into the test area.

The passive device consists of polypropylene plastic in the form of a 2.5-centimeter-long tube and contains two small tubes and cotton with a repellent. Scientists attached 70 devices to a large military tent. The mosquitoes were then released to various spots outside the tent and nearly all were killed or exiled within 24 hours.

“We call our device passive because you don’t have to do anything to activate it,” the scientists said. Its action is not limited to the fight against mosquitoes. The device can also protect against other insects.
